Frequently Asked Questions - AHX13CR SHARP

How to clean the air filters?

Turn off the unit, open the front panel, remove the filters by pushing them up then pulling them down. Clean them with a vacuum cleaner or wash them with warm water and a mild detergent. Dry them in the shade before reinstalling. Perform this operation every two weeks.

What to do if the unit does not cool properly?

Check that the filters are not dirty, that the air intake and outlet of the outdoor unit are not obstructed, that the thermostat is set correctly, that windows and doors are closed, and that no major heat source is present in the room.

How to use the remote control?

Insert two AAA (R03) batteries into the compartment respecting polarities. Point the remote control towards the unit's reception window at a maximum distance of 7 meters. Press the desired buttons. The unit emits a beep when it receives the signal.

Why does the unit make a rustling noise?

This noise is normal and comes from the circulation of refrigerant inside the circuit. It is not a malfunction.

How to set the timer off (TIMER OFF)?

Press the TIMER OFF button on the remote control. The TIMER OFF indicator flashes, use TIME ADVANCE or REVERSE to set the desired time (in 10-minute steps). Point the remote control at the unit and press SET/C. The orange TIMER indicator lights up on the unit.

What does blinking of the OPERATION, TIMER, and TEMPERATURE INDICATOR lights mean?

Blinking of these indicators indicates a malfunction. Contact after-sales service for inspection and repair.

Check the outdoor unit mounting rack periodically for wear and to make sure it is firmly in place. 5. Do not put anything on the outdoor unit nor step on it. The object or the person may fall down or drop, causing injury. 6. This unit is designed for residential use. Do not use for other applications such as in a kennel or greenhouse to raise animals or grow plants. 7. Do not place a vessel with water on the unit. If water penetrates into the unit, electrical insulations may deteriorate and cause electric shock. 8. Do not block the air inlets or outlets of the unit. It may cause insufficient performance or troubles. 9. Be sure to stop the operation and turn the circuit breaker off before performing any maintenance or cleaning. A fan is rotating inside the unit and you may get injured. 10. Do not splash or pour water directly on the unit. Water can cause electrical shock or equipment damage. 11. This appliance is not intended for use by young children or infirm persons without supervision. Young children should be supervised to ensure that they do not play with the appliance.

CAUTIONS FOR LOCATION / INSTALLATION

• Make sure to connect the air conditioner to a power supply of the rated voltage and frequency. Use of a power supply with improper voltage and frequency can result in equipment damage and possible fire.
• Do not install the unit in a place where inflammable gas may leak. It may cause fire. Install the unit in a place with minimal dust, fumes, and moisture in the air.
• Arrange the drain hose to ensure smooth drainage. Insufficient drainage may cause wetting of the room, furniture, etc.
• Make sure a leak breaker or a circuit breaker is installed, depending on the installation location, to avoid electrical shock.

ADDITIONAL NOTES ON OPERATION

D.B. = Dry-bulb, W.B. = Wet-bulb

• The built-in protective device may prevent the unit from operating when used out of this range.
• Condensation may form on the air outlet if the unit operates continuously in the COOL or DRY mode when humidity is over 80 percent.

WHEN POWER FAILURE OCCURS

This air conditioner has a memory function to store settings when a power failure occurs.

After power recovery, the unit will automatically re-start in the same settings which were active before the power failure, except for timer settings.

If the timers were set before a power failure, they will need to be re-set after power recovery.

NOTES FOR MODELS AY-X08CR/AY-X10CR/AY-X13CR

PREHEATING FUNCTION

In the HEAT operation, the indoor fan may not start for two to five minutes after the unit is turned on to prevent cold air from blowing out of the unit.

DE-ICING FUNCTION

• When ice forms on the heat exchanger in the outdoor unit during the HEAT operation, an automatic de-icer provides heat for about 5 to 10 minutes to remove the ice. During de-icing, the inside and outside fans stop operating.
• After de-icing is completed, the unit automatically resumes operation in the HEAT mode.

HEATING EFFICIENCY

• The unit employs a heat pump that draws heat from the outside air and releases it into the room. The outside air temperature therefore greatly affects the heating efficiency.
• If the heating efficiency is reduced due to low outside temperatures, use an additional heater. It takes time to warm up and heat the entire room because of the forced air circulation system.

TIPS ON SAVING ENERGY

Below are some simple ways to save energy when you use your air conditioner.

SET THE CORRECT TEMPERATURE

• Setting the thermostat 1°C higher than the desired temperature in the COOL mode (and 2°C lower in the HEAT mode with models AY-X08CR/AY-X10CR/AY-X13CR) will save approximately 10 percent in power consumption.
• Setting the temperature lower than necessary during cooling operation will result in increased power consumption.

BLOCK DIRECT SUNLIGHT AND PREVENT DRAFTS

• Blocking direct sunlight during cooling operation will reduce power consumption.
• Close the windows and doors during cooling operation (and heating operation with models AY-X08CR/AY-X10CR/AY-X13CR).

SET PROPER AIR FLOW DIRECTION TO OBTAIN THE BEST AIR CIRCULATION

KEEP FILTER CLEAN TO ENSURE THE MOST EFFICIENT OPERATION MAKE MOST OF THE TIMER OFF FUNCTION

DISCONNECT THE POWER CORD WHEN THE UNIT IS NOT USED FOR AN EXTENDED PERIOD OF TIME

• The indoor unit still consumes a small amount of power when it is not operating.
